Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations strongly indicate a safe, read-only, idempotent operation (readOnlyHint=true, destructiveHint=false). The description adds context about the inputs (branch protections and approval config) but does not describe output format, return behavior, or error handling. Since annotations already cover behavioral safety, the description provides moderate additional value without contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence of 16 words. Every word is necessary, and the core action and scope are front-loaded. No redundancy or unnecessary detail.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and only two parameters, the description should specify what the tool returns (e.g., a risk level string) and provide parameter semantics. It lacks both, leaving the agent unsure of the outcome and how to provide optional input. The tool's moderate complexity is not fully addressed.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, placing the burden on the description to explain parameters. The description mentions 'project’s branch protections and approval configuration' but does not directly map to the two parameters (project_id and target_branch). It omits explanation of what target_branch does (e.g., restrict assessment to a specific branch), leaving the AI agent unclear on usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('assess') and clearly identifies the resource ('project write risk') and the inputs considered (branch protections and approval configuration). It distinguishes this tool from sibling tools that merely retrieve project settings (e.g., gitlab_get_project_approval_configuration) by combining them into a risk rating.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies the tool should be used to evaluate mutation risk before write operations, but it does not explicitly state when to use it versus alternatives like gitlab_get_project_approval_configuration or gitlab_list_protected_branches. No exclusions or alternative tool mentions are provided, which limits its guidance for an AI agent.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, covering the safety profile. The description adds only that it 'highlights differences', which is a natural consequence of comparing. It does not disclose pagination, rate limits, or output format behavior beyond the schema, so the added value is minimal.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single 12-word sentence, very concise and front-loaded with the verb and resource. However, it is perhaps overly brief for a tool with multiple parameters, sacrificing completeness for brevity.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's moderate complexity (3 required parameters, one optional enum) and lack of an output schema, the description is insufficient. It does not explain the return format (e.g., what 'structured' or 'markdown' outputs look like) or the meaning of 'added, removed, changed jobs' in detail. Contextual completeness is low.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description provides no explanation of any parameter. The parameter names (project_id, left_pipeline_id, right_pipeline_id, output_format) are self-explanatory, but the description fails to clarify the meaning of output_format values ('structured' vs 'markdown') or any constraints beyond those in the schema. This is a significant gap for a tool with four parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly specifies the verb 'compare' and the resource 'pipeline runs', and states the output scope ('added, removed, or changed jobs'). It effectively distinguishes this from sibling tools that retrieve single pipelines (gitlab_get_pipeline) or list pipelines (gitlab_list_pipelines).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for comparing two specific pipeline runs but provides no explicit guidance on when to use this tool versus alternatives like gitlab_compare_refs or gitlab_get_merge_request_pipelines. No exclusions or context about prerequisites are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, destructiveHint. Description adds no additional behavioral context (e.g., result format, pagination, performance).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with key action. Could expand slightly without losing conciseness, but currently efficient.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 5 parameters, no output schema, and many siblings, description is too minimal. Lacks return value explanation, parameter details, and usage scenarios.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema has 0% description coverage; description mentions resources but does not explain parameter semantics (e.g., 'from', 'to', 'straight', 'unidiff'). Fails to add meaning beyond schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly specifies 'Compare' as verb and identifies resources: branches, tags, commits within a project. Distinguishes from siblings like pipeline-specific comparisons.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., gitlab_get_commit_diff, gitlab_compare_pipeline_runs). Missing context for appropriate invocation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds unique behavioral context (job output treated as untrusted) that helps agents understand the trustworthiness of returned content.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two sentences, front-loaded with purpose, and concise. It could include more detail on parameters or output without losing conciseness, but it is not overly verbose.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 5 parameters (2 required), no output schema, and annotations covering safety, the description lacks completeness. It does not explain default values (max_jobs=3, trace_tail_lines=40, output_format='structured'), enum options, or the return format. The note about untrusted output is useful but insufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must add parameter meaning. It only hints at 'max_jobs' and 'trace_tail_lines' implicitly through 'listing failed jobs and tailing their traces', but does not explain parameters like project_id, pipeline_id, output_format, or their constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool summarizes a failed pipeline by listing failed jobs and tailing their traces, which is a specific verb-resource combination. It distinguishes from sibling tools like gitlab_get_pipeline or gitlab_get_pipeline_failed_jobs_summary by adding the trace tailing component.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for failed pipelines but does not explicitly guide when to use this tool versus alternatives such as gitlab_get_pipeline_failed_jobs_summary or gitlab_list_pipeline_jobs. No when-not-to-use or exclusion criteria provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnlyHint=true, destructiveHint=false, and idempotentHint=true, so the safety profile is clear. The description adds behavioral context by specifying the filtering condition (detailed_merge_status), which is not obvious from annotations. However, it does not disclose pagination, rate limits, or response format.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no unnecessary words. It is appropriately concise but could be slightly expanded to include parameter usage or output hints without losing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and only 2 parameters, the description is insufficiently complete. It does not describe the return value (list of MR objects? counts?), nor does it provide parameter details or examples. This leaves an agent without crucial context for correct usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not mention any parameters. The 2 parameters (project_id, per_page) are left completely undocumented, forcing the agent to infer meaning from names alone.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states that the tool finds open merge requests with a specific 'detailed_merge_status' indicating a blocker, using a specific verb and resource. This distinguishes it from siblings like gitlab_list_merge_requests (lists all MRs) and gitlab_find_stale_merge_requests (finds stale MRs).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It does not mention when not to use it or suggest other tools for different scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, indicating safe reads. The description adds 'recent failed pipelines' but does not define 'recent' or clarify sorting/pagination behavior. It provides minimal additional context beyond the annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, which is concise but underspecified. It lacks needed details about parameters and behavior, making it insufficiently informative for the agent.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite simple requirements (3 params, no output schema), the description fails to explain what 'recent' means, how results are ordered, or how to use parameters effectively. Annotations help but do not compensate for missing param documentation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, meaning the JSON schema has no descriptions for the three parameters. The description does not mention any parameters, leaving the agent to guess that 'project_id' is required, 'ref' filters by branch/tag, and 'per_page' limits results. This is a critical gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'find', the resource 'recent failed pipelines', and the scope 'for a project'. This distinguishes it from siblings like gitlab_list_pipelines (lists all pipelines) and gitlab_get_pipeline_failed_jobs_summary (focuses on failed jobs within a pipeline).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Given the tool's simplicity (3 params, no output schema), the description is minimal. It omits typical commit fields returned (e.g., author, message, date), which an agent might need to anticipate the response. It is adequate but could be more informative.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The schema has 0% description coverage, so the description must add parameter context. It explains that the 'sha' parameter can accept a SHA, branch, or tag reference, which is helpful. However, it does not explain 'stats' or 'project_id'. This adds partial value but leaves gaps.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Retrieve' and the resource 'a specific commit', and specifies the means by SHA, branch, or tag reference. This distinguishes it from siblings like gitlab_get_commits (plural) and gitlab_get_commit_diff. However, the input schema only has a 'sha' parameter, which is somewhat inconsistent with the mention of branch or tag, creating slight ambiguity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives such as gitlab_get_commits, gitlab_get_commit_diff, or other retrieval tools. The description lacks context about use cases or exclusions, leaving the agent without direction for selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, providing a solid baseline. The description adds value by mentioning 'diff-size guardrails,' which alerts the agent to potential truncation or limits—a behavioral trait not captured by annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, succinct and front-loaded with the core action. However, it lacks structure (e.g., separate sections for when to use, parameters) and does not earn its place by also covering parameter details, which would improve clarity without much additional length.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 3 parameters, 0% schema coverage, and no output schema, the description is inadequate. It omits parameter explanations, return value format, error states, and edge cases like truncated diffs. The 'diff-size guardrails' hint is helpful but insufficient.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, yet the description does not explain any of the three parameters (sha, project_id, unidiff). The schema provides only field names and types, so the description fails to add meaning or usage context for parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'Retrieve the diff for a specific commit' with a verb and a specific resource. It also mentions 'diff-size guardrails,' which adds useful nuance and helps distinguish this from sibling tools like gitlab_get_commit (metadata) or gitlab_get_merge_request_diff (MR diff).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit when-to-use or when-not-to-use guidance is given. The description implies usage for specific commit diffs but does not mention alternatives like gitlab_get_merge_request_diff or conditions like large diffs being truncated. Sibling tools exist but are not referenced.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe, read-only operation. The description adds no further behavioral context (e.g., pagination, date filtering, or return format). With annotations covering safety, the description meets but does not exceed the baseline.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single short sentence with no wasted words, but it is overly terse. Conciseness should balance brevity with informativeness; here, the sentence is too minimal to be helpful. A longer description with essential parameter details would be more valuable.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 7 parameters and no output schema, the description is severely incomplete. It lacks information on pagination (page, per_page), date filtering (since, until), path filtering, and branch selection (ref_name). The agent cannot understand the tool's capabilities from this description alone.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not explain any of the 7 parameters (project_id, page, per_page, since, until, ref_name, path). A tool with multiple filtering parameters requires the description to add meaning beyond the schema, but it fails to do so. The agent cannot infer parameter usage from the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'List' and the resource 'repository commits', with the scope 'for a project'. It effectively distinguishes from sibling tools like 'gitlab_get_commit' (single commit) and 'gitlab_get_commit_diff' (diff), as well as code search tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives, no prerequisites, exclusions, or context about use cases. The agent receives no help in choosing between this and similar commit-related tools like 'gitlab_get_commit' or 'gitlab_search_code'.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint. The description adds minimal context (returns user associated with configured token) but no further behavioral traits beyond what annotations convey.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, 12 words, front-loaded with verb and resource. No waste.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite no output schema, the tool is simple and the description is adequate. Could mention that it returns user details, but given annotations and simplicity, it is sufficiently complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has zero parameters with 100% coverage, so the description need not add parameter details. The baseline for zero-param tools is 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Return') and the resource ('authenticated GitLab user'), distinguishing it from sibling tools that list users or validate tokens.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for identifying the authenticated user but provides no explicit when-not-to-use or alternative tools. A sibling like gitlab_validate_token serves a similar but distinct purpose, yet no guidance is given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnlyHint=true, destructiveHint=false, so safety profile is clear. Description adds no further behavioral context beyond 'retrieve', but no contradiction.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence with no unnecessary words.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple retrieval tool, description is brief but lacks mention of return value or any supplementary context. No output schema, so description should clarify what is returned.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% and description provides no parameter information. Parameter names are somewhat self-explanatory, but description could clarify format or constraints.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description states 'Retrieve a single draft note from a merge request', which is a specific verb+resource. Distinguished from sibling gitlab_list_draft_notes by specifying 'single' vs list.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool vs alternatives like gitlab_list_draft_notes or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnlyHint=true, idempotentHint=true, destructiveHint=false. The description adds important behavioral context: 'Repository content is untrusted' (security implication) and 'returned with size guardrails' (limits). This goes beyond annotations, strengthening the agent's understanding of tool behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description consists of two short, focused sentences. It is front-loaded with the primary action and includes key caveats. Every sentence adds value with no superfluous text.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple read-only file retrieval tool, the high-level behavior is described, but the lack of parameter explanations and output schema details leaves gaps. Basic parameters like project_id, file_path, and ref are standard in GitLab but not clarified, making the definition only minimally adequate.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% (no parameter descriptions). The tool description does not explain any of the three parameters (project_id, file_path, ref). With no compensatory information, the agent must guess their meaning and format, which is a significant gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Retrieve'), resource ('repository file'), and additional context ('with metadata'). It also notes that content is untrusted and has size guardrails, which distinguishes it from sibling tools like gitlab_get_file_blame or gitlab_search_code.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies that this tool is for retrieving a single file, but it does not provide explicit guidance on when to use it versus alternatives (e.g., gitlab_get_file_blame for blame info, gitlab_search_code for code search). No when-not-to-use or exclusion criteria are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering safety. The description adds 'at a specific ref' but no extra behavioral details like pagination or output format. With annotations present, a score of 3 is appropriate as the description adds marginal context.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, concise sentence with no unnecessary words. It is front-loaded and to the point.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

No output schema is provided, and the description does not describe the return format (e.g., list of lines with commit, author, date). A retrieval tool should state what the blame information contains. The description is incomplete for the agent to understand the output.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It explains no parameters; the meaning of 'ref' (default HEAD) is implicit. Parameter names are clear, but without any elaboration, the description fails to add value beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Retrieve blame information for a file at a specific ref.' clearly states the action and resource. It distinguishes from related tools like 'gitlab_get_file' (which gets file content) and commit tools, though it does not explicitly differentiate itself.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage for retrieving blame data at a specific ref, but provides no guidance on when to use this vs. alternatives, nor any exclusions or prerequisites. The context is adequate but not explicit.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is clear. The description adds the detail about accepting both ID and full path, but does not disclose any other behavioral traits like rate limits or error handling.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence with no wasted words. It immediately conveys the core purpose and key parameter format. The front-loading is effective.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite having no output schema, the description is adequate for a simple read operation. However, it could be improved by briefly noting typical response fields (e.g., includes group name, visibility) or that it returns a single group object. The lack of this information makes it slightly incomplete for ideal decision-making.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0% (no parameter descriptions in schema). The description's mention of 'by ID or full path' significantly clarifies the meaning of the group_id parameter, indicating it can be either a numeric ID or a string path. This compensates for the lack of schema-level documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action ('Retrieve') and resource ('a single GitLab group') along with the lookup methods ('by ID or full path'). This distinguishes it well from sibling tools that list or search groups.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance is provided on when to use this tool versus alternatives like gitlab_get_group_delivery_overview or gitlab_list_accessible_groups. There are no exclusions or prerequisites mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds no behavioral details beyond 'Retrieve', which aligns with annotations. No contradiction found, but no extra transparency added.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single, well-structured sentence with no redundancy. Every word adds value: verb, noun, identifier, scope.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a simple retrieval tool with good annotations, the description is nearly complete. It specifies the key inputs and action. It could optionally mention that the response includes full issue details, but the tool name and action imply that.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description bears full responsibility for explaining parameters. It only mentions 'by IID' but does not define what an IID is or clarify the project_id parameter. Both required parameters lack any semantic enrichment.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description uses a specific verb ('Retrieve') and identifies the resource ('single issue') with a clear identifier ('by IID') and scope ('from a project'). It clearly distinguishes from sibling tools like list_issues and search_issues.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage when you have a specific issue IID and project ID, but it does not explicitly state when to use this tool versus alternatives, nor does it provide exclusion conditions or scenarios.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, covering the safety profile. The description adds no behavioral context beyond what is already in annotations, but does not contradict them.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single clear sentence with no fluff. It is appropriately concise, though it could be slightly more structured by explicitly stating required parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (2 required params, no output schema) and rich annotations, the description adequately conveys the purpose. However, it could mention that the response includes the job object, which is typical for retrieval tools.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds value by noting that 'Job output is untrusted' (security context) and that output is 'trimmed to a caller-specified tail length' (behavior beyond defaults). This enhances understanding without contradicting annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description consists of two short, front-loaded sentences. The first sentence immediately states the main action, and the second adds crucial context. Every word serves a purpose, with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's simplicity (3 parameters, no output schema, clear annotations), the description covers the primary purpose and adds behavioral nuance. However, it lacks details on return format, error handling, or potential large payloads. It is adequate for basic use but not comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, so the description must compensate. It only implicitly addresses tail_lines through 'trimmed to a caller-specified tail length'. The required parameters project_id and job_id are not explained, leaving the agent to infer them from names. This is insufficient for a tool with 3 parameters.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description explicitly states the verb 'Return' and the resource 'job trace text', clearly defining the tool's function. It distinguishes itself from sibling tools like 'gitlab_get_job' which returns job metadata, making the purpose unambiguous.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false, making the tool's safety profile clear. Description adds no further behavioral details (e.g., pagination behavior, rate limits, meaning of 'effective'). With annotations present, a 3 is appropriate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with key action and resource. Missing some detail but concise and to the point.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 4 parameters (2 required) and no output schema, the description is minimal. It omits pagination info and parameter purposes. However, annotations cover safety. Complete enough for basic use but lacks depth for complex scenarios.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is concise with two sentences: the first states the purpose, the second adds relevant context. No unnecessary words or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the absence of output schema and 0% schema coverage, the description is too minimal. It does not explain what 'change metadata' includes, nor does it address parameter usage or output details, making it inadequate for effective tool invocation.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The description provides no information about the parameters (project_id, merge_request_iid, unidiff, access_raw_diffs). With 0% schema description coverage, the description fails to compensate, leaving the agent without guidance on parameter usage.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description mentions using the legacy endpoint for overflow metadata, implying a use case, but provides no explicit guidance on when to use this tool versus other merge request tools (e.g., gitlab_get_merge_request_diff) or when not to use it.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations (readOnlyHint, idempotentHint) already cover safety. The description adds no extra behavioral context beyond listing commits. No contradictions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence with no redundant words. However, it is so brief that it sacrifices completeness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Despite low complexity, the description lacks details on pagination, output format, or ordering. With no output schema, the agent is left uninformed about the response.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 0%, and the description does not clarify parameter semantics (e.g., 'project_id' may be ID or path, 'merge_request_iid' is not defined). Parameter names are self-explanatory but incomplete.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'list' and the resource 'commits that are part of a merge request', distinguishing it from sibling tools like gitlab_get_commit (single commit) or gitlab_get_merge_request_changes (diff stats).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives (e.g., gitlab_get_merge_request_changes for file changes). No context on prerequisites or use cases.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations (readOnlyHint, destructiveHint, idempotentHint) already cover safety and idempotency. The description adds that it lists diffs, confirming read-only behavior. No contradictions. Slight gap: does not mention pagination, but acceptable given annotation coverage.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with purpose, no filler words. Efficient and to the point.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema and missing parameter descriptions, the description is minimal. However, given the tool's simplicity and strong annotations, it is marginally adequate but not fully complete for agent usage.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, and the description does not explain any of the 4 parameters (project_id, merge_request_iid, page, per_page). The agent has no semantic guidance for parameter usage beyond names and types.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool over alternatives, such as when to prefer it over 'gitlab_get_merge_request_changes' or 'gitlab_get_merge_request_commits'. No context or exclusion criteria are given.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and openWorldHint. The description adds value by revealing that it auto-fetches later pages to include older notes, a behavioral trait beyond annotations. It does not mention auth or rate limits, but for a read-only tool the extra pagination info is significant.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with the purpose front-loaded and no extraneous words. Every sentence adds value: the first states what the tool does, the second provides key behavior.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has 5 parameters and no output schema, the description is too brief. It lacks information on required parameters and return format, leaving gaps for an agent. Annotations help, but the description should offer more guidance.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must compensate. It does not explain any parameters, not even the required project_id and merge_request_iid. It hints at pagination via 'auto-fetches later pages' but omits details on page, per_page, and max_pages.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description explicitly states the tool lists discussions for a merge request, using clear verb and resource. It distinguishes from sibling tools like gitlab_get_merge_request_commits or gitlab_get_merge_request_pipelines by focusing on discussions.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies usage by stating it lists discussions, but does not explicitly say when to use this tool versus alternatives or provide exclusion criteria. The auto-pagination hint is useful but not a full usage guide.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds no additional behavioral context (e.g., pagination behavior, default page size). With rich annotations, a score of 3 is appropriate as it does not add but also does not contradict.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence with no wasted words. It is appropriately front-loaded and easy to parse. However, it could include more information (e.g., parameter hints) without sacrificing conciseness.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of output schema, 0% schema coverage, and the presence of sibling tools, the description is incomplete. It does not describe the returned data (list of rule objects), pagination behavior, or how approval rules differ from configuration. More detail is needed for an agent to use this tool effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, meaning no parameter descriptions exist in the schema. The description does not explain the parameters (project_id, page, per_page), other than implying project_id identifies the project via the phrase 'project-level'. This is inadequate for agent usage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'List project-level merge request approval rules' uses a specific verb and resource, clearly indicating the tool's purpose. However, it does not differentiate from sibling tools like gitlab_get_project_approval_configuration or gitlab_get_merge_request_approval_rules, which could cause confusion.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool aggregates project dashboard data including open merge requests, open issues, recent pipelines, and attention highlights. The verb 'Aggregate' and listing of specific data types distinguishes it from sibling tools like 'gitlab_list_issues' or 'gitlab_get_project'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. The sibling list includes many related tools (e.g., gitlab_list_issues, gitlab_list_merge_requests, gitlab_list_pipelines), but the description does not explain what scenario justifies using an aggregate tool over fetching individual lists.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the description's job is reduced. However, it adds no extra behavioral context like the output format or any rate limits, which would be helpful. No contradictions with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single concise sentence with no unnecessary words. Every word adds value, stating the purpose directly.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and a single parameter, the description should specify the return format (e.g., a map of language to percentage) to fully inform the agent. It lacks this detail, making it incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description should elaborate on the 'project_id' parameter. It only mentions 'project repository' but does not explain what a project_id is or how to find it, leaving the agent to infer from the parameter name.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Return' and the resource 'language breakdown for a project repository', which is specific and distinct from sibling tools that deal with other project aspects.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool, such as recommending it for language statistics retrieval, or when not to use it (e.g., for other project data). No alternatives are mentioned.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false. Description adds value by clarifying that 'effective' members include inherited group memberships, a behavioral trait not captured in annotations. No contradiction found.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, direct and front-loaded. No extraneous words. Efficiently communicates core functionality.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Missing important context: what 'effective' means beyond inheritance, what the response contains (given no output schema), and pagination behavior. For a list tool with 4 parameters, the description is incomplete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the tool description provides no parameter information. Parameters like project_id, page, query, per_page are left undefined. The agent must rely solely on property names, which is insufficient for correct use.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states 'List effective project members, including inherited group memberships'. Verb (list) and resource (project members) are specific. Qualifiers 'effective' and 'including inherited' distinguish from sibling tools like list_group_members or list_accessible_projects.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives (e.g., list_group_members). No prerequisites, exclusions, or context provided. The agent must infer usage from the description alone.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate read-only, idempotent, and non-destructive behavior. The description adds that it returns statistics, which is a subtle behavioral detail not captured by the annotations. However, it does not explain any data retrieval specifics or potential limitations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, precise sentence with no redundancy. It is appropriately sized for a simple tool with one parameter.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has no output schema and a single parameter, the description provides minimal context. It mentions repository and storage statistics but omits details about the response structure or any other behavioral notes that would help the agent interpret results.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, the description should clarify the single parameter (project_id). It does not, leaving the agent to infer meaning solely from the parameter name and type. This is inadequate compensation for the missing schema descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool returns repository and storage statistics for a project. This distinctively differentiates it from sibling tools like gitlab_get_project (general project info) and gitlab_get_project_activity (activity data).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides no guidance on when to use this tool versus alternatives. It does not mention prerequisites, edge cases, or situations where another tool would be more appropriate.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false. The description adds no new behavioral context beyond restating the read-only operation. No contradiction with annotations.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single sentence that is front-loaded with the verb and key information. Every word serves a purpose, with no redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The tool is a simple read operation, but the lack of parameter descriptions means incomplete guidance. Output schema is absent, but for a retrieval tool, return type is partially inferable. Overall adequate but not comprehensive.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

The input schema has 0% description coverage, meaning neither field (project_id, tag_name) has a schema description. The tool description does not elaborate on what project_id or tag_name should be, leaving agents to infer their meaning. This is a significant gap.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the action (Retrieve), the resource (a single project release), and the key parameter (by tag name). It distinguishes from sibling gitlab_list_releases, which returns multiple releases.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies that this tool is for fetching a known release by tag, but it does not explicitly mention when to use it versus siblings like gitlab_list_releases or gitlab_get_project. No alternative guidance is provided.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already convey readOnly, idempotent, non-destructive, and openWorldHint. The description adds 'metadata' but lacks details about return format or performance characteristics. With rich annotations, description provides marginal additional value.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded, zero waste. Every word earns its place.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no parameters and no output schema, the description is adequate. However, explicitly stating that it returns version string would improve completeness.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Tool has zero parameters and schema coverage is 100%. The description correctly adds no parameter info, as there are none. Baseline for 0 parameters is 4.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

Description clearly states it returns version metadata of the GitLab instance, using a specific verb and resource. No sibling tool provides version info, so it is well-differentiated.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies use for retrieving version info, which is straightforward. No explicit exclusions or alternatives are needed given the simplicity, but could mention it's for checking instance version.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint, idempotentHint, and destructiveHint, so the safety profile is clear. The description adds the allowlist filtering behavior. However, it does not disclose pagination, rate limits, or error behavior.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single sentence, which is concise but omits critical parameter details. It is front-loaded with the core purpose but is too sparse for a tool with multiple parameters.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With 4 optional parameters, no output schema, and minimal description, the tool definition is incomplete. It does not cover pagination, search behavior, or the meaning of min_access_level, leaving the agent to infer or experiment.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Input schema has 4 parameters with 0% description coverage. The description does not explain any parameter (page, search, per_page, min_access_level), leaving the agent without semantic understanding beyond what the schema provides.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states 'List groups accessible to the configured token', specifying the verb and resource. It also mentions filtering by allowlist, adding context. However, it does not explicitly distinguish from sibling tools like gitlab_search_groups, which could cause ambiguity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives like gitlab_search_groups. The description does not provide context for usage, exclusions, or prerequisites.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already indicate readOnlyHint, openWorldHint, idempotentHint, destructiveHint. The description adds that results are based on token permissions and filtered by allowlists/deny lists, which is useful but vague.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

A single clear sentence with no redundancy. Efficiently communicates the core action and constraint.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given 6 optional parameters and no output schema, the description omits important details like pagination, filtering behavior, and result scope. Incomplete for an agent to use effectively.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0% and the description does not explain any of the 6 parameters (page, search, etc.). No value added beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists projects accessible to the token, with filtering from allowlists/deny lists. It distinguishes from siblings like 'search_projects' by implying it returns a pre-filtered set, though not explicit.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance provided on when to use this tool versus alternatives like 'search_projects' or 'list_accessible_groups'. The description lacks context for selection.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations declare readOnlyHint=true, destructiveHint=false, openWorldHint=true, idempotentHint=true, so the agent knows it's safe and read-only. The description adds no further behavioral context (e.g., pagination, sorting), but the annotations already cover the safety profile adequately.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
